In this project-based tutorial, I will show you how to use the Gemini 3 API to build multi-agent applications that use a CSV dataset provided by the user and perform deep data analytics. 

In short, the multi-agent app will perform:

• Simple analytics: Quickly explore the dataset structure and basics.
• Code generation: Use Gemini 3 Pro to create advanced analysis code with visualizations.
• Secure execution: Run the code in a sandboxed environment and save results.
• Intelligent reasoning: Analyze and interpret findings for key insights.
• PDF report compilation: Generate a polished PDF with visuals and clear explanations, insights graspable in seconds.
